Garry,
I'm assuming you are looking for the rivets and associated brackets that hold the aluminium trim to the body?
If so, then you would need the following:
a) clip A001 988 54 78 (x3)
b) rivet N910 001 003 100 (x6)
c) bracket A113 698 00 14 (x3) - these are a bit overpriced at 18 Euros each...
The above is still available from the Classic Centre.
Coincidentally, the aluminium trim piece is also still available (A113 698 00 81) for about 77 Euros.
